A new species of Hyperolius is described from Nyungwe National Park in southern Rwanda. The new species differs fromits congeners by a unique combination of morphological characters, including a light green dorsum and a transparentventral skin resembling glass frogs of the Neotropical family Centrolenidae, blue-coloured bones, reduced toe webbing,relatively wide head, acuminate snout, small to medium size (SUL of adult males 18.8–23.2 mm), and the presence ofnuptial pads. The advertisement call differs from all calls of other species of the genus that have been analyzed.Comparison of the mitochondrial 16S rRNA gene showed a relatively close relationship to H. castaneus, H.cystocandicans, H. discodactylus, H. frontalis, and H. lateralis. The 16S sequence of the new species differs by at least 4.5% in the uncorrected p-distance from all available sequences of other species of the genus.Ubwoko bushya bwa Hyperolius buboneka muri parike nasiynali ya Nyungwe mu majyepfo yu Rwanda.

A New Species

We describe a new species of megophryid frog in the genus Leptolalax from the Kon Tum Plateau in northeastern Cambodia. Leptolalax melicus sp. nov. is distinguished from its congeners by a combination of an off-white to pale pink ventral surface with diffuse dark brown blotches and distinct white speckling, finger I < II, an absence of webbing and dermal fringes on fingers, slight basal webbing and no dermal fringes on toes, body size (19.5–22.7 mm for seven adult males), an absence of ventrolateral glandular lines, dorsum mostly smooth with no skin ridges, and a unique advertisement call consisting of a single long introductory note containing 8–50 pulses, followed by 3–11 predominantly single-pulsed notes, and with an average dominant frequency of 3560–3610 Hz. Leptolalax melicus can be further distinguished from the morphologically similar L. applebyi in having more distinct dorsal patterning, and significantly larger pectoral and femoral glands. Leptolalax melicus and L. applebyi also differ by 6.1% sequence divergence at the 16S mtDNA gene. All specimens of L. melicus were found near rocky streams in evergreen forest between 650–850 m elevation. We suggest the new species should be considered Data Deficient following IUCN’s Red List categories.

Here we describe a new species of the toad genus Amazophrynella (Bufonidae) from the south margin of the Amazon River in Santarém, state of Pará, Brazilian Amazonia. The new species can be diagnosed by (1) medium body size for the genus: adult females 19.5–20.4 mm SVL, adult males 13.0–14.5 mm SVL; (2) snout acuminate in lateral view; (3) Finger I larger and robust; (4) Finger I nearly equal in size than Finger II; (5) palmar tubercle rounded, covering ¼ of hand; (6) pigmented callus in Finger I in males; in life: (7) brown stain on throat and chest; (8) black dots on venter. Males emit two distinct advertisement calls: the call type 1 consists of a relatively long note (mean 0.248 s) with a mean dominant frequency of 3526 Hz. The call type 2 is arranged in bouts of 6 to 22 notes with mean dominant frequency of 3450 Hz and much shorter note durations (mean 0.034 s). In this study we also redescribe the advertisement call of A. minuta, which also emits a second call type.

A New Species

We describe a new species of small megophryid frog from the Langbian Plateau in southern Vietnam, the southernmost record of Leptolalax from Vietnam. Leptolalax bidoupensis sp. nov. is distinguished from its congeners by a combination of a dark brownish red ventral surface with white speckling on entire ventral surface including throat, arms and legs, small size (23.6–24.6 mm in four adult males and 29.2–29.4 mm in two adult females), bicoloured iris (coppery red upper half, fading to pale silver ventrally), a mostly smooth skin texture with no skin ridges, and relatively short tibia (male TIB:SVL 0.44–0.46). The male advertisement call of the new species, consisting of 6–9 single-pulsed notes with a dominant frequency of 1.9–3.8 kHz, is also unique among Leptolalax species for which calls are known. From the morphologically similar L. applebyi and L. melicus, L. bidoupensis sp. nov. differs by 9.3% and 9.6% sequence divergence at the 16S mtDNA gene. At present, the new species is known from montane evergreen forest between 1620–1730 m elevation, within an area of 1 km 2 . We suggest the species should be considered Data Deficient following IUCN’s Red List categories.

A New Species

A new species of frog in the genus Microhyla is described from Sumatra, Indonesia based on molecular and morphological characters. This new species was previously confused with M. achatina, a Javan endemic. This new species is diagnosable from its congeners by possessing a medium size (SVL in adult males 18.20–21.32 mm, in adult females 20.37–25.51 mm), a stout body, a nostril–eyelid length being about half of the snout length, having a single outer palmar tubercle, a tibiotarsal articulation reaching the center of the eye (when the hindlimbs are stretched and adpressed to the body), having finger and toe tips dilated, having the dorsum with medial longitudinal grooves, and excibiting a very thin and short dark stripe on the temporal region above a wider cream stripe, extending from the postorbital area to insertion of forelimb. Additionally, the new species is characterized by possessing relatively little foot webbing. Uncorrected 16S rRNA sequence divergences between the new taxon and sequences for other congeneric species available ranged from 4.8 to 15.0%.

A New Species

The small nurse frogs of the genus Allobates (Anura, Aromobatidae) represent one of the most challenging taxonomic issues of the Neotropics. During several amphibian surveys in the Middle Tapajós River region, state of Pará, Brazil, we collected phenotypic, ecological, and molecular data on species of this genus, leading to the identification of a new species included in the Allobates masniger-nidicola complex. The new species is characterized by a large body size (snout-vent length 19.2–21.7 mm in males and 19.3–22.0 mm in females), finger III not swollen in adult males; cryptic external coloration, with dorsum uniformly ochre; a dark brown lateral stripe and a pale cream ventrolateral stripe; limbs ranging from ochre to orange; throat and chest violaceous in males and yellowish in females. The advertisement call is usually arranged in bouts of four closely spaced notes, which we term 4-pulsed units of repetition (UR), 0.317 s long on average, followed by silent intervals, and an average dominant frequency of 4.163 kHz. The new species also has exotrophic tadpoles with a unique fin morphology, which begins after the body-tail insertion and is deeper posteriorly to half of the caudal length. Sequencing of the 16S and COI regions of the mitochondrial DNA show a genetic p-distance of approximately 6–10% compared to closely related congeners. We discuss the biogeography of the new species based on phylogenetic relationships of the species within the Allobates masniger-nidicola complex and the allopatric geographic distribution in relation to sister taxa. Functional characteristics and geographic restrictions make this species particularly sensitive to the increasing human impact in eastern Amazonia.

We describe a new species of Leptolalax from central Vietnam. Leptolalax firthi sp. nov. is distinguished from its congeners bya combination of the following characters: an absence of distinct dark brown or black dorsolateral markings; toes with rudimen-tary webbing and wide lateral dermal fringes in males and weak or absent lateral dermal fringes in females; most males withwide lateral dermal fringes on Finger II; medium size (26.4–29.2 mm in 21 adult males, 25.7–36.9 mm in 14 females); and nearimmaculate white chest and belly. The male advertisement call of the new species, consisting of 2–5 notes with a dominant fre-quency of 5.4–6.6 kHz (at 18.3–21.2º C) is also unique among Leptolalax species for which calls are known. Uncorrectedsequence divergences between L. firthi and all homologous 16S rRNA sequences available were >10%. At present, the newspecies is known from montane evergreen forest between ~860–1720 m elevation in Kon Tum and Quang Nam Provinces. Theextreme sexual dimorphism observed in L. firthi in terms of lateral dermal fringing, a morphological character often used to dis-tinguish Leptolalax species, highlights the importance of ensuring interspecific comparisons in the genus are performed separately for each sex.
